Deluuuc

We'll be sailing with Celebrity for the first time next March and we decided to stay in The Retreat category. Do retreat guests need to pre-book specialty restaurants in order to guarantee seats, especially at the most popular restaurants. We want to dine at Eden on The Edge ship but not sure when we want to eat there during our sailing.

When pre booking for the entertainment 26 days in advance, were you able to do it online or did you have to call NCL concierge?
